A 65kg driver is poised at the edge of a 10.0m high platform. Calculate the gravitational potential energy associated with the position of the driver. Assume the zero level is at the surface of the pool.

6.37 kJ

Explanation:

The formulae for calculating gravitational potential energy is;

GPE = m * g * h  where;

m – mass (kg)

g – gravity (m/s2)

h – height (m)

= 65 * 9.8 * 10

= 6,370 joules

= 6.37 kJ

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

your answer is c) plasma
